The aim of the study was to determine the prevalence of snow crab sensitisation and occupational asthma.
Prevalence study of symptoms, pulmonary function testing and allergy testing to crab was conducted in four crab plants of different design in Newfoundland and Labrador, Canada.
Plants workers in four crab plants were interviewed and offered skin testing, RAST, pulmonary function testing and peak flow monitoring before and during crab processing.
38% (n=78) had atopy. 18% (n=39) had certain or highly probable crab asthma. The prevalence of sensitisation in different crab plants varied from 50% (n=19) to 15% (n=16) and the prevalence of certain or highly probable crab asthma varied from 50% (n=19) to 9% (n=3).
Crab asthma and sensitisation to snow crab is a major health problem for snow crab plant workers in Newfoundland and Labrador.
本研究旨在确定雪蟹致敏和职业性哮喘的患病率。
在加拿大纽芬兰和拉布拉多省四家设计不同的蟹类加工厂，对症状、肺功能测试和蟹类过敏测试进行患病率研究。
对四家蟹类加工厂的工人进行访谈，并在蟹类加工前和加工期间进行皮肤测试、放射变应原吸附试验、肺功能测试和峰值流量监测。
38%（n = 78）有特应性。18%（n = 39）有确定或高度可能的蟹类哮喘。不同蟹类加工厂的致敏患病率从50%（n = 19）到15%（n = 16）不等，确定或高度可能的蟹类哮喘患病率从50%（n = 19）到9%（n = 3）不等。
蟹类哮喘和对雪蟹的致敏是纽芬兰和拉布拉多省雪蟹加工厂工人的主要健康问题。
